Description
Technical field
The present invention relates to solar energy photovoltaic glass technical fields, more particularly to suitable for the height of double-glass solar energy assembly backboard
Reflectance coating and preparation method thereof.
Background technique
Silicon materials are a kind of semiconductor materials, and solar cell power generation principle is mainly exactly the photoelectricity using this semiconductor
Effect.Silicon refractive index is very big, and the light for being irradiated to silicon face cannot be sufficiently absorbed, but is greatly reflected, in order to
Reflection loss is reduced to the maximum extent, be can be used and is plated one or more layers refractive index and thickness and the matched anti-reflection of battery on battery
Film is penetrated to improve the transformation efficiency of battery.The transmitance of light can be increased by crossing coated with antireflection film, so that the efficiency of battery is improved, it is porous
Silica dioxide antireflection film not only makes the transformation efficiency of battery improve 5%~6%, but also the cracking resistance that matrix can be improved is strong
Degree.
In recent years, solar double-glass assemblies are quickly grown, application especially harsher in climatic environment.It is white in addition to using
The encapsulating material of color, such as EVA and POE overleaf coat white highly-reflective coating, become a kind of effective promotion group on glass
The solution of part efficiency.The highly-reflective coating material so some producers and scholar begin one's study, the product of country's listing is also very
It is rare, the almost external import that double-glass solar energy assembly producer uses, not only price, and with domestic glass
Associativity is also somewhat poor, is easy to scrape and wipe, not high to visible reflectance (about 78% or so), and whiteness is low (about 80 or so).If
Glass can be increased to 80% or more to visible reflectance, 82 or more whiteness, the efficiency of battery component can be improved 3%~6%.
Summary of the invention
That it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of bond strengths is high, at low cost, whiteness is high,
The high highly-reflective coating product of reflectivity, to meet the service performance requirement of enterprise well, to may advantageously facilitate double glass too
The technological progress of positive energy component industry and application development.It is suitable for double glass solar energy another object of the present invention is to provide above-mentioned
The preparation method of the highly-reflective coating of component backboard.

Above-mentioned highly-reflective coating provided by the invention is realized by the following method: inorganic binder is molten by 1350 DEG C
Melt rear quenching, ball milling is carefully to requiring granularity after drying, according still further to formula composition by nm-class rutile-type TiO 2 and nano-sulfur
Sour barium weighing enters to be mixed together dispersion, and powder is beaten in then precipitating drying, then carries out grinding distribution with load weighted varnish, i.e.,
Ink product is obtained, the method for ink silk-screen printing is coated in solar energy back-panel glass, by 680~720 DEG C of baking 2-5
Minute is to get highly-reflective coating product.
The invention has the following advantages:
(1) highly-reflective coating product of the present invention, the low and associativity with glass of production cost is good, is not easy to scrape.
(2) matching of the inorganic binder coefficient of expansion and glass prepared by the present invention, glass will not deform, and intensity improves.
